The Broadway actress whose daughter was mowed down and killed in a Brooklyn crosswalk, has lost the baby she was carrying at the time of the crash, the family's lawyer told the Daily News Wednesday.

Ruthie Ann Miles and her husband Jonathan Blumenstein were expecting the baby girl this month.

"At the time of the crash Ruthie was pregnant and was severely injured. This past Friday Ruthie and Jonathan lost their baby, Sophia Rosemary Wong Blumenstein," Ben Rubinowitz said. "The pain suffered by Ruthie and Jonathan is nearly impossible to fathom."

Miles and Lauren Lew were crossing 9th St. at Fifth Ave. in Park Slope with their young children when Dorothy Bruns blew a red light and slammed into them on March 5.

Miles' daughter, Abigail, 4, and Lew's 1-year-old son, Joshua, died in the wreck.

The Staten Island woman's license was suspended two days after the crash.

Bruns racked up eight tickets from red-light and speed cameras prior to the smash up.

Earlier this month, she was charged in a 10-count indictment for getting behind the wheel of her Volvo S60 against her doctor's orders, knowing she was a deadly crash waiting to happen.

Bruns hit a city housing Authority worker six months prior to the fatal accident, injuring the woman's shoulder, ankle and wrist and then driving away. The worker got Bruns' license plate number and filed a report, but police never followed up.

"This should never happen," Mayor de Blasio said after a Daily News report detailing Bruns history. "She should never have been allowed to be driving a car after what we know."

Miles earned a Tony in 2015 for her performance in "The King and I." She was 39 weeks pregnant when she lost her baby Friday, Rubinowitz said.

Prosecutors won't be able to pursue additional charges, since state laws regarding homicide only apply after a baby is born, according to the state statute.
